There are three main types of combustion chambers discussed in the document: multiple, annular, and tubo-annular. The multiple type has individual burner cans that are easier to dismantle but take up more space. The annular type is more compact and efficient. The tubo-annular type combines aspects of the annular and multiple types for maintenance and efficiency benefits. It discusses the basic design and benefits of each type.

4. • Each interconnected can has its own fuel
injector, igniter, liner, and casing; all acting as
an individual burner units
• The interconnectors are required for flame
propagation during ignition and for even
pressure
distribution
throughout
the
combustion section. (flame propagation tubes)

6. • Air from the compressor enters each
individual chamber through a transition
section.
• Combustion occurs within the inner
liner.
• Louvers and holes control airflow into
the combustion area.

• a high resistance to
warpage because of
large degree of

9. Annular

10. • Annular inner and outer AIR CASINGS
form a tunnel around the centre line of
the engine
• The FLAME TUBE is located in the
space between the inner and outer air
** provides a larger casing.

11. • USAGE: both small and large engines
• MOST EFFICIENT: thermal efficiency,
weight, and physical size
• Process: similar to multiple-can design
• Maintenance: removed as a single unit;
complete separation of the engine at a
major flange.

14. • The “Half-Way House”
• combination of both annular (outer shell) and
can-type (number of cans) designs mounted
about the engine axis.
• Inner combustion chamber casing: serves as
structural support and a heat shield
• Bearing oil supply lines run through it

15. • was invented by Pratt & Whitney
• removable steel shroud= encircles the entire
combustion section.
• multiple burner cans assembled radially
around the engine axis can-annular
combustor (ease of maintenance) contains
individual burner cans in an annular liner

17. Summary
• Multiple- earlier engines usage; simple
to dismantle; bulky
• Tubo-annular- more compact, with a
smooth exterior and reduced weight
• Annular system- much more compact
system and, same power output and
mass flow, shorter upto 25% length
